EMB-190 pilot reported a Slat Failure during approach. The flight crew requested priority handling and made a precautionary landing at destination airport.

Narrative

We arrived to a dark jet for our early flight from ZZZ1 and completed a power up procedure. Shortly after power up we got a Slat Fail EICAS message. We powered down; had GO (Ground Operations) disconnect ground power from the jet and completed a second power up on APU. The same message reappeared. Under direction of Maintenance Control; we powered down and powered back up on APU with a 7 minute wait in between. Once powered up we ran several diagnostic tests which failed. We then powered down for Local Contract Maintenance. After powering up the Slat Fail message was no longer present but was replaced by a Cyan Slat LO Rate EICAS message; a deferrable item.The flight was normal until immediately prior to descent into ZZZ at which point the Slat Fail EICAS returned. We ran the appropriate QRH procedure and determined that the slats would not extend out of the zero position. We [requested priority handling] with ATC and notified Maintenance Control of the EICAS message. We then notified Inflight and issued them a Code X color followed by a brief. We then followed up with an announcement to our customers. We landed and taxied to the gate without incident. After parking at the gate I made an aircraft maintenance logbook entry stating 'Slat Fail in Flight. Slats would not move from the zero position'. The attached picture is of the EICAS in flight before landing.
